Previous studies have shown the impact of family, community, and ethnic networks on migration. Our research focuses on the role of social networks in Hungarian internal migration. We examine the factors determining out-migration rate from municipalities, and the factors influencing location...

We provide evidence for the causal pro-trade effect of migrants and in doing so establish an important link between migrant networks and long-run economic development. To this end, we exploit a unique event in human history, i.e. the exodus of the Vietnamese Boat People to the US. This episode...

This paper introduces the idea that the network structure that emerges from a foreign-born population's internal migration process changes the conditions for international immigration. The idea is tested by using data from the period between 1998 and 2008 about virtually all internal and...

We use the Immigrants Admitted to the United States (microdata) supplemented with special tabulations from the Department of Homeland Security to examine how family reunification impacts the age composition of new immigrant cohorts since 1980. We develop a family migration multiplier measure for...

Experimental observations of cell migration often describe the presence of mesoscale patterns within motile cell populations. These patterns can take the form of cells moving as aggregates or in chain-like formation. Here we present a discrete model capable of producing mesoscale patterns. These...
